ABSTRACT
Chronic pain significantly impairs functional performance in patients with cancer. Although acupuncture is effective for cancer-related pain, its impact on pain-related functional interference remains unclear. This secondary analysis of the PEACE randomized clinical trial included patients with prior cancer diagnoses and musculoskeletal pain for ≥3 months. Participants were randomized to groups undergoing 10 weeks of electro-acupuncture, auricular acupuncture, or a waitlist control. Functional performance was assessed using the Quick-Disability Arm/Shoulder/Hand (Q-DASH) for upper limbs and the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) subscale for lower limbs (higher scores = worse function). Linear mixed models compared changes over time between groups, with week 12 as the primary endpoint. Functional changes were also compared between pain responders and non-responders in the acupuncture arms. Among 360 patients (mean [SD] age, 62.1 [12.7] years; 69.7% women), mean baseline Q-DASH and WOMAC scores were 33.2 (19.8) and 33.3 (20.3). At week 12, both electro-acupuncture and auricular acupuncture significantly improved function versus waitlist: Q-DASH by -7.18 and -9.64 points, respectively, and WOMAC by -6.89 and -7.61 points (all p < 0.001). No differences were found between the two acupuncture groups. Treatment effects on Q-DASH diminished during follow-up, while improvements on WOMAC persisted. Within the acupuncture groups, pain responders achieved greater functional gains than non-responders (Q-DASH, -6.74; WOMAC, -6.16; both p < 0.001). Electro-acupuncture and auricular acupuncture improved upper and lower extremity function in cancer patients with chronic pain. These findings support acupuncture as a potential adjunct in functional rehabilitation for cancer survivors.
